PoO/Z [T 57512} B M A240 r9r TORNEYS United States Patent 3,199,945 GREASE BANDAGE STRUQTURE Robert E. EStutz, Memphis, Tenn, assiguor to Chapman The present invention relates to an improved wood preservative bandage and more particularly to a package having outer sheets which are separable to expose layers of grease on their inner surfaces to provide, a bandage and wherein improved opening facilities are provided for the package to insure the separation of the layers of grease and obtain a more effective bandage.

There are various methods of applying preservatives to wood prior to the time the wood is put in use or after it is put in use and one of the primary uses of the present invention is for extending the life of poles already in the line. Some of these poles may have been in place many years and the application of a bandage bearing a wood preservative grease composition will add extra life to the years of the poles. These poles which were poorly treated or pretreated with inferior preservatives may again be treated while in place, with the application of the bandage of the instant invention, and poles which are removed from one location to be set in another, frequently at a different depth, can be advantageously treated. The bandage of course may have uses in many applications.

The bandage serves a dual function in providing an applicator and support for the grease preservative when it is applied to the pole in the field, and provides a package for the preservative protecting it for shipping, handling and storing up to the time when it is used in the field. It is imperative that when the package is opened in the field to expose the preservative and provide the bandage for application to the wood, that the opening be simply and easily effected for expedient application to the wood and for optimum distribution and effective application of the preservative. In a bandage of the type embodying the features of the instant invention, an outer sheet of wood preservative greaseimpervious material is provided folded together to, in effect, form upper and lower outer sheets, and the wood preservative is spread in a layer on the inner surfaces of these outer sheets. The outer sheets are sealed at their edges to form a closed package, and in order that the layers of grease will stay with the outer sheets when they are separated to expose the grease and form the bandage, separator sheets are placed between the layers. While these separator sheets effectively separate the layers of preservative, it is often difiicut to start them separating and frequently necessary to use fingers, a pointed object, such as a stick, knife or trowel, to separate the separator sheets at a corner or edge when open ing the package. It is difiicult to locate the line of separation between the separator sheets and they frequently become embedded in the grease during attempts to separate them, and the fingers or other objects become coated with the grease creating an undesirable situation.

It is accordingly an object of the present invention to provide an irnproved'wood preservative grease bandage formed into a package wherein the package is rapidly and easily opened, and the layers of grease within will stay with the outer sheets in uniform layers, and separator sheets between the layers of grease will separate without the necessity of a separate operation.

A further object of the invention is to provide an improved structure for a grease preservative bandage which maintains the separation between separator sheets within the bandage and insures their clean and uniform separation with the opening of the bandage.

3,199,945 Patented Aug. 10,- 1965 A still further object of the invention is to provide an improved structure in a grease preservative bandage wherein one end of a separator sheet is attached to the end of an outer sheet in an improved and effective manner, without adversely affecting the greaseproof integrity of the closed bandage.

Other objects, advantages and features will become more apparent with the teaching of the principles of the invention in connection with the disclosure of the preferred embodiments thereof in the specification, claims and drawings, in which:

FIGURE 1 is a top plan view of a wood preservative bandage formed into a package in accordance with the principles of the present invention;

FIGURE 2 is a prespective view illustrating a step in opening the bandage;

FIGURE 3 is a plan view showing the bandage in opened position;

FIGURE 4 is a sectional view taken substantially along line IVIV of FIGURE 1 illustrating the interior construction of the bandage; and

FIGURES 5, 6 and 7 are views similar to FIGURE 4 illustrating modifications in the structure for attaching the end of the separator sheet to the outer sheet.

As shown on the drawings:

FIGURE 1 illustrates the bandage in its closed position or in other words, formed into a package 10 for handling and storing the bandage. The open bandage is shown at 11 in FIGURE 3, andFIGURE 2 illustrates the bandage as it is being opened to expose thev wood preservative grease 16 therein.

The bandage is formed with an outer sheet which for convenience is made integral and doubled at its edge 12a to form an upper outer sheet 12 and a lower outer sheet 13, and the upper and lower sheets form one continuous sheet when the bandage is opened, as shown in FIGURE 3. The outer sheet is formed of a siutable protective material which will provide support for the wood preservative and must be impervious to the wood preservative grease. A kraft paper coated on its inner surface with a thermoplastic is well suited, and the edges of the closed package 10 are joined by a seam 14 which can be heat sealed to close the package.

To open the package and form the bandage 11, the upper outer sheet 12 is lifted or drawn away from the outer lower sheet 13 to expose the layer of wood preservative grease 16 which is spread on the inner surface thereof. While the layer of grease I6 is formed integral, when the outer sheets 12 and 13 are doubled to form the package 10, the two sides of the layer 16 of grease are brought together so that they may be regarded as an upper layer 16a and a lower layer 16b of grease spread over the upper and lower outer sheets 12 and 13.

In order that the layers 15a and 16b will separate, sheets 18 and 19 of separator material are placed therebetween. The relative positions of these materials is shown in FIGURE 4. The separator material in accordance with the principles of the present invention must have sufficient tensile strength to be pulled at its end without tearing and to draw the upper layer 16a of wood preservative grease away from the lower layer 1611. A material such as crinoline is well suited for the present purposes. Materials which are extremely soft or become permeated with the grease to lose their tensile strength are unsatisfactory.

In accordance with the principles of the present invention it is also required that the end edge of the upper separator sheet be non-yieldably and firmly attached to the upper outer sheet 12. Such attachment as occurs merely by the adherence of the grease is unsatisfactory since it will not insure separation of the layers of separator material 18 and 19, and there is no assurance that the adhesion caused by the grease between the two separator -layers themselves will not be as strong as the adhesion between the upper separator layer and the upper outer sheet.

Accordingly, as shown in FIGURE 4, the upper separator layer 18 is positively attached to the upper outer sheet 12 by a separator sheet attachment strip 21. The attachment strip is made of a material suited for bonding to thecrin'oline separator sheet 18 and tothe inner surface of the outer sheet 12, and may be for example made of F a razor blade, knife or other sharp object which cuts through the upper sheet 12 inside of the seam 14 along the cutting line 15. When this is accomplished the upper outer sheet 12 is lifted upwardly away from the lower sheet 13,-and its layer 16a of grease will stay with it inasmuch as the upper separator sheet 18 is lifted therewith in the manner shown in the dotted line position in FIG-- URE 4, and as shown in FIGURE 2.

Meanstare provided for gripping the upper sheet 12 at a separation starting location, which in FIGURE 2 is shown as the corner of the package 10. A preferred 'arr'angement for gripping the sheet 12 is accomplished by the provision of a pull tab 17 of paper or similar material which is suitably attached as by an adhesive to the outer surface of the upper sheet 12.

FIGURE 5 shows another arrangement for attaching the upper separator strip 18 to an attachment strip 24 which is mounted at 26 to the upper outer sheet 12. The strip 24 is doubled to form a fold 25, and the end 20 of the upper separator sheet 18 is positioned in the fold and bonded therein. This bonding may be accomplished such V as by stitching, or by heatsealing the layers formed by the fold.

In FIGURE 6, the upper separation sheet 18 of crinoline is extended to form a long end 27, and the long end is laid along the inner surface of the upper sheet 12. To permit heat sealing the crinoline directly to the upper sheet, a pair of sandwiching strips 28 and 253 are provided to bind the crinoline end 27 therebetween. The sandwiching strips can be attached directly to the upper sheet without the danger. of pinholing along the seal and subsequent leaking which is possible if the crinoline is attempted to be attached directly to the inner surface. The

.inner sandwiching strip 28 in efifect provides an extra layer of coating.

In FIGURE 7 the upper separating sheet 18 has an extended end 30 which is doubled rearwardly so as to'lay along the inner surface of the upper outer sheet 12, and the end 30 after being folded is placed between sandwiching strips 31 and 32 which in turn are bonded to the upper outer sheet 12.

Each of the arrangements of FIGURES 4 through 7 functions to positively and non-yieldably attach the end of the upper separator sheet 18 to the upper outer sheet 12. If desired, a suitable adhesive may be used to replace the heat seal bond. A suitable inner coating for the outer sheets is a polyester film, and a strip of polyester or polyester coated paper may be utilized for the sandwiching strips or attachment strips described above in connection with FIGURES 4 through 7.

In operation, the package 10, FIGURE 1, is taken from storage and when at the location Where the bandage is to be applied, is out along the line-15 to separate the upper outer layer 12. The layer 12 is then lifted by manually gripping the tab 17 in the manner shown in FIGURE 2. Lifting the upper outer sheet 12 will positively draw the upper separator sheet 18 away from the lower separator sheet 19 starting at the outer edge thereof so separation will be automatic and sure. This action is illustrated in the dotted line position of FIGURE 4.' I

Thus it will be seen that I have provided an improved bandage and package structure for containing wood preservative grease which greatly facilitates handling, storage and use in the field and the separation of the layers to form the bandagehas been accomplished without in any way impairing the greaseproof integrity of the package. 7

The drawings and specification present a detailed disclosure of the preferredv embodiments of the invention, and it is to be understood that the invention is not limited to the, specific forms disclosed, but covers all modifications, changes and alternative constructions and methods falling within the scope of the, principles taught by the invention. a i
